The rate-distortion optimization (RDO) method in the H.264/AVC encoder is an informative technology that improves the coding efficiency, but increases the computational complexity. In this letter, a fast Intra mode decision algorithm using DCT (Discrete Cosine Transform) coefficients distribution is proposed to reduce the H.264 encoder complexity. The proposed method reduces the encoder complex...

Consider a discrete-time remote estimation system formed by an encoder, a transmission policy, a channel, and a remote estimator. The encoder assesses a random process that the remote estimator seeks to estimate based on information sent to it by the encoder via the channel. The channel is affected by Bernoulli drops. The instantaneous probability of a drop is governed by a finite state machine...

We demonstrate that an attention-based encoder-decoder model can be used for sentence-level grammatical error identification for the Automated Evaluation of Scientific Writing (AESW) Shared Task 2016. The attention-based encoder-decoder models can be used for the generation of corrections, in addition to error identification, which is of interest for certain end-user applications. We show that ...

This paper illustrates a real-time implementation of MPEG-2 (BC) layer 1 and layer 2 stereo encoder on a Pentium-III platform. It describes the architecture and features of Pentium-III, suited for real-time implementation of stereo encoder. Further, the MPEG audio encoder algorithm and techniques used in optimizing the individual modules for Pentium-III environment are explained. Finally, the p...

INTRODUCTION Angular encoder accuracy is often the key limiting factor in rotational metrology systems. Inconsistent spacing of the graduations and spindle error motion are major sources of encoder error. Through calibration, the repeatable components of encoder error can be eliminated. Calibration systems have been developed to measure the error map at 128 angular intervals, achieving 0.01" (a...

The rate-distortion optimization (RDO) method is an informative technology that improves the coding efficiency, but increases the computational complexity, of the H.264 encoder. In this letter, a fast Macroblock mode determination algorithm is proposed to reduce the computational complexity of the H.264 encoder. The proposed method reduces the encoder complexity by 55%, while maintaining the sa...

This paper presents a new method to increase the available measurement resolution of quadrature encoder signals. The proposed method features an adaptive signal correction phase and an interpolation phase. Typical imperfections in the encoder signals including amplitude difference, mean offsets and quadrature phase shift errors are corrected using recursive least squares with exponential forget...

In this paper, Continuous Phase Modulation (CPM) is investigated. We employ the decomposed CPM model where the model is decomposed into a Continuous Phase Encoder (CPE) and a Memoryless Modulator (MM). This allows us to concentrate on the encoding aspects without interference from the modulator. By designing a convolutional channel encoder (CE), to operate over the same algebra as the CPE, the ...

An Artificial Neural Network-based error compensation method is proposed for improving the accuracy of resolver-based 16-bit encoders by compensating for their respective systematic error profiles. The error compensation procedure, for a particular encoder, involves obtaining its error profile by calibrating it on a precision rotary table, training the neural network by using a part of this dat...
